BUILDING TRIM Regis=W.. Stalter, Pitt'sburghplaa Application- January21, 1950",,ser1e1' No. 13918751 (CL 20 -5 )L' 2" Claims; I

My invention relates to buildings whose outer walls are finished withclapboards, and more particularly to means for trimming the ends of theclapboards at" the corners of such walls, as well as the edges ofdoorways and windows formed in the buildin walls.

Heretofore, many devices have beenproposed. to finish the cornersanded'ges of'clapboardwalls, but there" are certain objections to. alloff them. My invention consists in certain new and useful improvementsin such devices, whereby greatest economy in manufacture andi'nst'ali'ation is realized, and greater architectural. and. structuralmerit are obtained.

The invention will. be. understood. upon referenceto the accompanyingdrawings-inwhicht Fig. 1 isa fragmentary View inperspective. of a smallhome whose windows, .doors. andlcorners are finished with a trimstructure of my invention;

Fig. 2is an exploded'view,,illustrating fragrmentarily the side wallofthehomeat theright band edge of one of the windows, andishowing; thetwocomponents of a trim structure impositions for assembly;

Fig. 3 is. a fragmentary perspective. view] of the two elements of. thetrim structure in the relative positions in which. they are arranged.

building shown in Fig. 1;. and

Fig; 4 is a view similar to Fig. 3,isho.wing,.the;

corner trim elements in. positionv for. assembly. upon" the right-handcorner. of the building.

Referring to Fig. l, a one-story building.- is.

shown fragmentarily. The building has four walls; the front wall 2' and"one of the two. side walls3 and ct'appea'ring'in the View. A doorway 5and-'twowindows 5' are provided in the. fiiont wall. The walls are facedwith clapboard or lap-siding formed of strips 'la'pplied andrecured.upon the outer surfaces of the inner or basal walls 8 (Fig; 2) of thebuilding: The inner or basalwalls' 8- may consist of wooden boards. orcomposition boards, or other suitable sheeting material; carried by theusuaiwooden scantlings (not shown)", and" mayhave the usual liner ofwater-proof felt paper; or the like, appliedbetween the" inner walls"and the clapboard strips 1. The clapboard siding may be formed of" 2herein: Alternately; the siding" may be formed of a compositionboard? orof metal, such as street steel; aluminum, or the like; embossed orstamped to provide the stepped or lapped effect when the siding" isapplied" to the building walls.

The" trim structure of this invention" is de signed to finish theexternal vertical edges of' the doorway and windows of" the building; inorder toprovide not merely the desired neat finish" of the edges; butalso toa'iford' an overlapped;

snug and weather-tight engagement" of the trim with theclapbo'ardsiding;

It will" be understood that the clapboard or" lap siding ashitherto"usually applied; is" butted against the window; door'orcover trim. Inthe trim structure of my invention clapboard sic?- in'g" strips need notbe butted against the" trim.

Morespecifically; the trim of this'invention is" not required? that is,the ends of the. clapboard.

strips, being overlappedlastheyare by the trim structure, need. notbeexactl'y. evenon flush. A- great deal ofltiine of the workmenin-making accurate measurements. is. thus. saved.

The trim structure. inwhich my. invention is foundv comprises abasalstrip 9. and a. finish. strip IOi. Ordinarily thetrim-strips? 9iand [-0 will be. formed of' wood} but. aluminum-,compositionboard or.othersuitable material is-held in contemplation. In. application thebasal strips; 9 are nail'edor. otherwisesecured to-theverticah sideedges ofJJthe doorway 5 or windows 6 Re.- ierrin'g to Fig. 2;, the wayin which the. tr-inr is. applied to the. right-hand" edgeo'fi the.window 6 will suffice for an' understanding. of; how the trim.

isapplied to both of the verticall edges of each Thebasal.

window; andoft'he' doorway, 5 as welli. strip" 9 isfnailedl'upon" theouter. face: of'the. inner.

wood'emstrips; as they'are shownin' thedrawings' Wall'- or siding 8; insuch position that the edge Pi'eces' 'of strip" that" are out too short:

3 9a is substantially fiush with the edge 8a of said inner wall. Thestrip portion 9 extends vertically from the basal sill of the window tothe top of the window opening, and a similar basal strip 9 is applied inequivalent manner to the left-hand edge of the window, which is notshown in Fig. 2, but will be understood upon reference to Fig. 1. Suchbasal strips 9 are applied to the vertical edges of both of the windowsand the door in the particular wall (2) on which the clapboard siding isto be applied.

When the basal trim members 9 have been thus secured in place, theclapboard strips 1 are applied, with the strips cut to such length that,within the vertical extents of the doorway 5 and windows 6, the ends ofthe strips are positioned against, not necessarily accurately abuttedagainst, the adjacent sides of the basal trim members 9. It is importantto note that the outer faces of the basal trim members 9 are of steppedform, including a series of facets 91), whereby the outer face of eachbasal trim member is of the same stepped formation as the outer surfacesof the applied clapboard strips 1. The facets 9b are laterally alignedseverally with the outer surfaces of the applied clapboard strips. Whenthe clapboard siding has been applied, the finish strips ID areinstalled to complete the installation.

The finish strips l are of greater width than the basal strips 9, and ontheir inner or under faces they are of stepped form, including facetsIllb which are the exact complement or counterpart of the facets 9b ofthe basal strips 9. The strips [0 are applied with their facets [0bsnugly fitted upon the facets 9b of the basal strips 9, and with theassembled strips 9 and in precisely aligned at their inner edges, thatis, the edges which form the vertical finish edges of the window anddoor openings. The strips I 0 (being wider than basal strips 9) extendlaterally from strips 9 and overlap the ends of the clapboard members 1,and the facets Illb of the strips [0 snugly engage the outer surfaces ofthe clapboard siding, forming in each instance a perfect weather-proofunion II (Fig. 1), a union of neat and pleasing appearance.

At the inside or inner edges of the door and window openings the strips9 and I0 meet in a pencil-line seam of saw-tooth form, as shown, whichis substantially invisible, particularly after the building has beenpainted. The tops of the windows and doorway are finished with top trimsI2, as shown, and the joints are finished by means of trim pieces I3which in this case are fiush with the inner or inside edges of theassembled trim strips 9 and I0.

The two-part trim structure 9, ID of this invention has other advantagesthan those already mentioned. For example the same trim structure isadapted for use on both the right-hand and left-hand sides of thewindows and doorway. It will be readily understood that the basal stripsmay be cut from stock milled to saw tooth form on its outer face, asdescribed, and the strips 9 thus cut to length may be applied to bothsides of each opening to be treated. After the clapboard siding isinstalled, the finish strips I0, cut from stock milled to saw-tooth formon its inner face, are applied on the outer faces of the strips 9. Thefinish strip on the right-hand side of the opening is extended to theright from the basal strip to overlap the adjacent ends of theclapboards, while the finish strip on the lefthand side of the openingis extended to the left of the basal strip for the same purpose. Thus, asingle inventory of stock, from which strips 9 and I0 can be cut, may becarried by the mill and/or th building contractors, thereby dispensingwith the necessity of stocking right-hand and left-hand parts.

The structure of the invention is also applicable with equal advantagesfor trimming the corners of the building. The principal modification inthe structure for the corner trim 90, I00 is found in the basal member.As shown in Figs. 3 and 4, the modified basal member is of saw-toothform on two of its contiguous, longitudinal edges or faces A and B,providing on face A a line of facets 90a, on face B a line of facets90b. By virtue of this particular form, the basal member or strip 99 maybe used on any of the corners of the building. In Fig. 1 only twocorners of the illustrated building are shown, the left-hand cornerformed by the intersection of the walls 2 and 3, and the right-handcorner formed by the intersection of walls 2 and 4.

In applying the trim structure to the left-hand corner of the building,a basal strip 90, cut to proper length from milled stock, is appliedafter the clapboard siding has been installed on wall 3. The strip 90 isplaced with its facets 90b overlapped upon the ends of the clapboardsiding members on wall 3. The facets 90a are aligned or extend severallyin common planes with the outer surfaces of the clapboard siding memberson front wall 2. The finish trim strip I00 may be identical in form withthe finish strip IU of the structure already described, having one edgeor face of saw-tooth form, with a series of stepped and inclined facetsIOOb that are complementary inform and arrangement with the facets 90aand/or 9% on the basal strip 90.

When the basal strip 99 has been applied to the left-hand corner of thebuilding, as described above, the finish strip I00 is then nailed orotherwise secured upon the basal strip, with the facets l00b of thefinish strip snugly engaging the facets 90a of the basal strip, asindicated at 90a, I09b at the left of Fig. 1. The finish strip is widerthan the basal strip, and the strip extends laterally (to the right) ofthe basal strip, overlapping the ends of the clapboard on front wall 2,with the extended portions of facets IUUb snugly fitted upon the outerfaces of the clapboard siding on said wall.

The same trim structure is used to provid the trim on the right-handcorner of the building, as will be understood upon considering Fig. 1.The trim members 90 and H10 are interchangeable as indicated in thedrawings, for the finish of both right-hand and left-hand corners of anybuilding faced with clapboard, or the like, and advantages of the natureindicated are obtained in largest measure.

Within the terms of the appended claims many modifications andvariations may be made, without departure from the spirit of theinvention.

I claim:

1. A trim for the corner formed by two intersecting building walls facedwith clapboard siding, said trim comprising a basal strip of sawtoothform on each of two contiguous longitudinally extending edges, one ofsaid saw-tooth edges (hereinafter called edge A) having facets arrangedfor alignment with the outer surfaces of the clapboard siding on one ofsaid walls, the other of said saw-tooth edges having facets overlappedand fitted upon the outer surfaces of the clapboard siding on the otherof said walls, and

a finish strip of saw-tooth form havin facets on its inner face arrangedto be secured in snug engagement with the facets of saw-tooth edge A andextended laterally therefrom for overlapped engagement with the outersurfaces of the clapboard siding with which the facets of said saw-toothedge A are severally aligned, the engaged basal and finish strips beingadapted to present in the external corner surfaces of the building asingle saw-tooth seam.

2. A building structure having a wall With a clapboard siding, a trimfor a corner of the building structure comprising a basal stripextending along the ends of the clapboards at said corner, the outerface of said basal strip being of'saw-tooth form having facets locatedbeyond said ends of the clapboards and in registry severally with theouter surfaces of the clapboard siding, and a finish strip of saw-toothform on REG-IS W.
